茶园蜘蛛、昆虫群落动态的研究

该文研究报道了皖南地区茶园蜘蛛、昆虫的种类和群落结构,结果如下:1.茶园中昆虫、蜘蛛种类有28个,其中5、6月群落中动物种类多,多样性指数大。调查期内,品种园内动物优势种是天敌。2.主成分分析(PCA)表明:在无人为干扰的品种园内,节肢动物群落结构稳定;进行化学防治的采摘茶园群落结构不稳定。此研究对于在茶园内合理使用农药、繁荣生物群落,提高茶叶品质有重要意义。

STUDY ON THE COMMUNITY DYNAMICS OF SPIDERS AND INSECTS IN TEA PLANTATION GARDEN

Species of spiders and insects and their community structure in the tea plantation garden (Xuan Langguang Tea Corporation) in the south of An-hui province have been studied.The results from the study shows that there are 28 pecies of insects and spiders in the garden, most of which are alive in May and June with a higher diversity index. During the period of investigation,, the dominant species of animal were found to be the natural enemies in the veriety tea plantation garden. The principal component analysis (PCA) indicates that arthropod community has a more stable structure in the veriety tea plantation garden without anthropogenic disturbance than in those with plucking and chemical control of pests.
